Prefiring method for an ink-jet head and apparatus having the ink-jet head with the prefiring method |
摘要 |
An apparatus having an ink-jet head has a time measuring unit, a recording unit, and a prefiring operation control unit. The time measuring unit is used to measure an elapsed time from execution of prefiring operations for the ink-jet head, and the recording unit is used to record whether or not printing nozzles disposed in the ink-jet head are operated. The prefiring operation control unit determines a number of prefiring operations in accordance with a measurement result obtained by the time measuring unit and operated conditions of the printing nozzles recorded in the recording means, and executes prefiring operations for the ink-jet head. Therefore, the apparatus is capable of executing prefiring operations often enough and sufficient for the actual operated conditions of the printing nozzles disposed in the ink-jet head, and thereby preventing ink from being consumed at enhanced rate by useless prefiring operations.
